First, match each word to its corresponding code using numbers that appear more than once.

Secondly, work out what each letter is in code.

Thirdly, work out the word, in this case DRINK, using the code you have found.

So let’s give it a try!

There are two codes beginning with the number 2. Do we have any words starting with the same letter?

We have two words starting with the letter C, so 2 must represent C (2=C).

We have two codes with the number 4 in the second letter position. Which letter appears in the second letter position twice? 4 must be the letter A (4=A).

We now have enough information to match each word to a code, giving us:

DARK = 0473

CRAB = 2741

CARD = 2470

INKS = 8935

So D = 0, R = 7, I = 8, N = 9, K = 3.

If we use this code on the word DRINK, we get the answer of 07893.

In this activity, you will be a code cracker and work out the digit-based code for a given word.

Pssstt!! Here’s a handy hint to help you reach superstar status:

It can be really helpful to write the words out and then write the corresponding numbers above each letter as you work them out. Give it a go!

Here is a list of words:

TILL DULL TIDE GATE

Here are some codes for the above words. They are not necessarily in order:

5733 2033 2054 9624

Using this information, what would be the code for ALTITUDE?

CORRECT ANSWER

63202754

EDDIE SAYS

OK, code cracker. These questions can take a bit longer to explain. Let's go through it step by step.
1. Match each word to its corresponding code using numbers that appear more than once:
There are two codes beginning with the number 2.
We have two words starting with the letter T, so 2 must represent T (2 = T).
We have two codes with the number 3 repeated twice at the end of the word. The letter L is repeated twice at the end of two words. So, 3 must be the letter L (3 = L).
We now have enough information to match each word to a code, giving us:
TILL = 2033
DULL = 5733
TIDE = 2054
GATE = 9624
2. Work out what each letter is in code:
So A = 6, L = 3, T = 2, I = 0, T = 2, U = 7, D = 5, E = 4
3. Work out the word:
If we use this code on the word ALTITUDE, we get the answer of 63202754.
I hope that makes sense! Take your time over these questions - they can be tricky at first, but you'll get there!

1. Match each word to its corresponding code using numbers that appear more than once:
There are three codes ending with the number 3, so 3 must represent E (3 = E)
We have two codes in which the number 1 appears in the position of the third letter. So 1 must represent M (1 = M)
We have two words which begin with the letter L and two codes which begin with the number 5. So, 5 = L.

CORRECT ANSWER

194460

EDDIE SAYS

Did you spot that the letter E was repeated in a few words and that the number 3 was repeated in a few codes, code cracker? This will have given you a great starting point if so!
1. Match each word to its corresponding code using numbers that appear more than once:
The number 3 appears three times in various positions (fourth letter, third letter, first letter). So number 3 must represent the letter E (3 = E).
The number 4 appears once in the position of the first letter and once in the position of the last letter. Therefore, the number 4 must represent the letter M.
We now have enough information to match each word to a code, giving us:
MUSE = 4913
STEW = 1035
WHIM = 5264

1. Match each word to its corresponding code using numbers that appear more than once:
Did you spot that one of the words is made up of five letters and the others are all four letters? This makes it easy to spot which one is the code for CHOSE - it has to be 92134.
Having worked that out, it is easy to sort out all the others because we now know the code for c, h, o, s and e!
We now have enough information to match each word to a code, giving us:

1. Match each word to its corresponding code using numbers that appear more than once:
There are two codes ending with the number 6 . We have two words ending with the letter E, so 6 must represent E (6 = E).
We have two codes with the number 4 in the third letter position. The letter S appears in the third letter position twice. So 4 must be the letter S (4 = S).

EDDIE SAYS

Did you show good CHARACTER and persevere through this question, code cracker? Keep that effort up right until the end!
1. Match each word to its corresponding code using numbers that appear more than once:
We have four codes ending with the number 2. All the words end with the letter E. So 2 must be E (2 = E).
We have two codes with the number 4 in the second letter position. The letter O appears in the second letter position twice. So 4 must be the letter O (4 = O).
We have the number 3 appearing in two codes, as the first letter in one code and in the third letter position in the other. The letter C appears as the first and the third letters so 3 must be C. (3 = C).
We now have enough information to match each word to a code, giving us:
RACE = 9032
CODE = 3462
HOPE = 1472
TAPE = 5072
2. Work out what each letter is in code:
So C = 3, H = 1, A = 0, R = 9, A = 0, C = 3, T = 5, E = 2, R = 9

How did you get on with that last question, code cracker? Will you bear with me whilst we go through one final explanation? It will be worth it in the end!
1. Match each word to its corresponding code using numbers that appear more than once:
There are two codes ending with the letter 2 used twice in a row (22). There are two words which end with a double letter (LL). So 2 must be L (2 = L).
We have two words beginning with the number 9 and two words which begin with the letter P. Therefore, 9 must be P (9 = P).
We now have enough information to match each word to a code, giving us:
PILL = 9122
